Managing Local State

[idkjs]

What would be the equivalent in this project of this code:

const IS_LOGGED_IN = gql`
  query IsUserLoggedIn { 
   isLoggedIn @client 
 }`

It found in the apollo docs here-> https://www.apollographql.com/docs/tutorial/local-state/.

I guess this is a query on the client which we would set up with cache?

Yes, assuming you've done the work of making it available in the cache you would use it just like normal:

[%graphql {|
  query IsUserLoggedIn { 
    isLoggedIn @client 
  }
|}]

The complication here is that you now need to account for this in your graphql_schema.json that graphql-ppx is consuming. We have some client state in our apps and I think I used some combination of graphql-tools and graphql-codegen to combine the schemas, but I don't know what would be best today. If you're just playing around, you could probably specify a separate schema for your client-only queries?

oh wow. got an error before when i tried using @client. Seperate schema....I can see conceptually how we would do that. I am going to try that. Be nice to have an example of some of these less used cases in the repo or docs so if I get it done, I will share it if you want it. Thanks for the feedback, sir.

Hmm yes this would be interesting to implement within graphql-ppx. However, I don't know if many people use this feature. I certainly don't use it and I don't really see direct benefits of using this instead of simple client state with useState.
